At JavaOne 2008 conference, Ben Alex from SpringSource talked about emerging security requirements in enterprise applications. He discussed the standards like Servlet Security, JAAS, CAPTCHA, Single Sign-On and Federated Identity using OpenID technology. The presentation also included the standards on securing web services (WS-Security), JMS messaging and ESB.

In a JavaOne presentation, Sun Microsystems’ Tony Printezis provided more details on Garbage First, a replacement for the CMS garbage collector particularly targeted at long running server applications.

On day 2 of JavaOne 2008 conference, Emmanuel Bernard talked about Bean Validation framework (JSR 303). The goal of this specification is to provide a uniform way to express and implement the constraints in java applications. Earlier in the day, Oracle team previewed the upcoming features of Oracle Fusion Middleware 11g.

So far, JavaOne has been heavy on JavaFX content. It is clear that a lot of work has been done since the initial announcement at last year’s conference. Although, the technologies do not appear to be ready for the typical developer.

At JavaOne 2008, Jos Dirksen and Tijs Rademakers talked about using Service Component Architecture (SCA) and Java Business Integration (JBI) frameworks together to get the best of both worlds. Using a sample application, they explained how to deploy an SCA application on a JBI container. In another SCA related session, Mike Edwards gave an overview of SCA architecture model.

Neal Gafter recently gave a presentation at JavaOne and Jazoon '07 entitled "Closures for Java". The presentation is an accessible but thorough introduction to closures, the goals, the problem with existing solutions, all presented in a conversational style.

Closing out the Java One conference last week was Rob Harrop's presentation "Exploiting JRuby: Building Domain-Specific Languages for the Java Virtual Machine." Domain specific languages (DSLs) have been gaining popularity, as shown on InfoQ with a presentation on an introduction to domain specific languages by Martin Fowler and posts on the debates in the blogsphere.

At Java One Thomas Bernhardt and Alexandre Vasseur explained the concepts of event driven application servers and the Esper project.
Event driven application servers are a new category of servers, proving a runtime and supporting infrastructure services (transport, security, event journaling, high availability, connectors, etc.) to servers designed to be able to process over 100,000 events/sec.

Java ME developers face many obstacles that server-side or desktop Java developers never have to contend with. Nokia, Sprint, and IBM teamed for a JavaOne session that outlined a solution to these problems through an service-oriented architecture based on OSGi

In a panel on the Service Component Architecture (SCA) at JavaOne, one of the controversive topics was the SCA client programming model. Moderator David Chappell and Gregor Hohpe share their impressions.

Missing from the keynote announcements at JavaOne was discussion on improving the deployment path of desktop Java applications. Hope may finally come later this year in the form a consumer targeted JRE however.
